The client may be trying to reuse the connection; see
http://en.wikipedia.org/wiki/HTTP_persistent_connection.  This seems
consistent with your results:

 * With the close call: connection is closed right after client sends a
second request, so client whines.

 * Without the close call: client waits around for a response, then gives
up and establishes another connection.

To confirm, add another receiveHTTP call client_interact and see if it
returns another Request.
